专题五 介 词,介词是一种用来表示词与词、词与句之间的关系的虚词，在句中不能单独作句子成分。介词后面一般有名词、代词或相当于名词的其他词类，短语或从句作它的宾语。介词和它的宾语构成介词词组，在句中作状语、表语、定语或宾语补足语。介词可分为时间介词、地点介词、方式介词、原因介词和其他介词。Nothing in the world could live without air or water.(状语)This machine is in good condition.(表语)Where is the key to my bike?(定语)She always thinks herself above others.（宾补）,一、介词的分类（1）从用法分类,（2）从结构分类,【考点一】考查with/without复合结构介词with/without+名词/代词+形容词/副词/介词短语/动词不定式/分词（分词可以是现在分词，也可以是过去分词）在句中表状态或说明背景情况，常作伴随、方式、原因、条件等状语。With all the things she needed bought,she went
